II'he .wagon box on crop reeeiwing portion As shown in Figure 2, the wagon elevator 22 is provided with an overshot conveyor 3| which delivers harvester crop upwardly on top of the conveyor bottoms 32 of the elevator 22 by reason of the regularly spaced cross slats or flight members 33. The upper and rearmost end of the wagon elevator 22 constitutes the discharge end 34 thereof through which the harvested and elevated crop is projected for deposit in the trailing wagon box 30.

Without auxiliary means and with a constant speed running elevator conveyor 3| the crop would be deposited in one position within the wagon box. This, of course, contributes to inefficient, uneven loading of the wagon and it is thus desirable to have means capable of disperw ing the harvested crop over the full area of the trailing wagon.

Thus, in order to accomplish this uniform spreading over the full surface of the wagon box 30, a crop-deflecting member or flap 35 is disposed within the discharge end 34 of the wagon elevator 22. As best shown in Figure 4 the dis charge end 34 includes a pair of spaced-apart side members 35 and 3'! between which is positioned the elevator conveyor and the deflector flap 35. The deflector member is amxed at its one end to a rod 38 which is journaled within the spaced-apart side plates 35 and 3'? and thus constitutes a hinge pin about which the flap 35 may be moved for various angular positions of the deflector within the discharge end 34 of the wagon elevator. As best shown in Figure 8, the hinge rod 38 has a downwardly bent end portion 39 adjacent to and just laterally outside of the side plate 36 of the discharge portion 34 of the wagon elevator. At the lower end of this bent end 39 there is a still further bent portion 44 which lies parallel to the main horizontal portion 38. It will thus be apparent that fore and aft swinging movement of the bent ends 33 and 4B of the hinge pin 38, as shown in Figs. 1, 2, 3 and 5, will cause the adjustable positioning of the deflector flap 35.

A bracket 4| is fixedly mounted by any suitable means such as welding to the side plate 38 and is equipped with an elongated slot 42 therein for lateral passage therethrough of a shaft 43 which carries a pulley 44. The pulley 44 receives the upper end of the conveyor belt-3| in the wagon elevator. It should be understood that the shaft 43 carried in a bearing 45 may be adjustably positioned at any location within the elongated slot 42 to effect proper tautness oi the conveyor belt 3|.

The bracket 4| is provided with spaced-apart parallel flanges 45 and 41. The forwardly disposed flange 41 has an opening 48 therethrough which is substantially rectangular in shape and includes four sides, the lower edge of which is identified by the numeral 49. A second opening 50 is provided in the flange 4! at a position spaced from the opening 48.

A relatively elongated member 55 in the form of a right angle is adapted for sliding through the rectangularly shaped opening 4% in the bracket flange 41. The member is hown, in detail, in several of the side views and in Figs. 7 and 8 wherein it is shown there is a substantially upright wall portion 52 and a bent-over or flanged top 53. Figure 8 further shows the attachment of the rearmost end of the member 5| to the portion 45 of the hinge shaft 38. The bent portion 40 of the hinge rod 38 passes through the member 5| and by reason of a cotter pin 54 the member 5| is held in position on the bent end 44 of the hinge rod. Endwise movement of the member 5| thus causes direct angular shifting of the deflector 35.

The member 5| has the lower edge of its verti cal wall 52 equipped with a series of regularly spaced notches 55. Each of the notches 55 has an inclined surface 55 and a relatively vertically positioned surface 5! extending upwardly from the lower edge 58 of the wall 52 of the member 5|. A rope 59 is attached to the forward end of the member 5| at 60. The forward end of the rope or flexible cable is attached at 5| to a position adjacent the operators seat l2 for convenient reaching by an operators hand. A spring 52 is anchored at 63 to the member 55 adjacent the rope attachment at 50. The spring 552 is of the coil extension type and passes rcarwardly through the opening in the flange 4? of the bracket 4| and is attached at its rear end at 64 to the spaced-apart flange 46.

As best shown in Figure 2, the forwardly disposed notch in the series of regularly spaced notches is positioned within the rectangular opening 48 in the flange 41 with the notch engaging the lower edge 49 of that opening. The

coil spring 62 is arranged in such a manner that there is constantly exerted a rearward and upward pulling of the member 5|, thus a forward and downward pulling of the flexible rope 59 by the tractor operator will pull the member 55 against the action of the spring 62 and cause the member 5| to ride along the inclined surface 55 of the notch in engagement with the lower edge 49 of the opening 48, thus causing the eventual engagement of the second of said notches with the ledge 49.

A separate plate member 65 is positioned against the back wall 52 of the elongated member 5|. The plate 65 is disposed beneath the top flange 53 of the member 5| and when the members 5| and 65 have relative movement with respect to each other the plate 65 slides on the under surface of the top flange 53 of the member 5|. The late 65 is relatively short compared to the length of the member 5| but its height exceeds the height of the member 5|. The lower edge of the plate 65 is designated by the numeral 66 and has cut therein a dual notch 67 which comprises a shallow cutout or slot 68 and a relatively deep slot 59. These slots 68 and 69 are joined by oppositely inclined walls 10 and The plate member 65 is arranged and constructed to be positioned within the rectangular opening 48 in the bracket 4| and is further positioned so that the dual notch 51 engages the lower edge 49 of the rectangular opening 48. When the device is in assembled position, as shown in the drawings, the plate member 55 remains within the opening 48 throughout all operations of the ad justing mechanism; however, the plate does have limited endwise movement within the opening 48 so that at various times during the operation of the device the shallow slot 68 will engage the lower edge 49 of the opening 48 and at still other times the deep slot 69 will engage the ledge 49.

As best shown in Figs. 2 and 3, the elongated member 5| is provided with spaced-apart projections 12 and 13 at the forward and rearward portions respectively. These projections are mounted on the vertical wall 52 of the member 5| and project inwardly in the same direction as the top flange 53. The projections thus are in thepath of the plate 65 and although under the majority of operations of the device of this invention the 5 member:- 5lrimoves separately totel'fect changes'in adjustmentrahereaare those special timeszwhen longitudinalwmovement nor 1 thew-member's 5| mx ill cause: a: concurrent longitudinal-movement er the plate: :6 5:.by: reason :of' the engagement/ f either of-tthe.;projections' J2 1 or 13hwith' theplate.

In the operation*of='the-device--*1et usassume that the wagon:=elevatorideflector e5 is in its uppermost position, as shown in Figs. 1 and 2, so that harvested material being carried .up. .the wagonfelevatori! will bedepos'ited in [.the'rear portion of the wagon box30. "In order to lower the deflector 35 the operator grabs hold of the rope 59 and pulls it forwardly, directly causing the member 5| to be pulled against the action of the spring 62, thus sliding the member 5| into the succeeding notch 55 on the underside of the member 5| for engagement with the lower ledge or surface 49 of the rectangular opening 48 in the bracket 4|. The inclined wall 'l| leading from the deep slot 69 to the adjoining inclined wall of the slot 68 has a depth greater than the depth of the notch 55 in the member 5|; thus, the plate member 65 remains longitudinally stationary with respect to the bracket 4| when the deep slot 69 engages the top surface 49 of the opening 48. The operator may therefore select any position for the member 5| merely by pulling and releasing the rope 59 and stopping in any one of the series of regularly spaced adjusting notches 55 whereupon the deflector 35 may be adjusted throughout the range of positions as best shown in Fig. 5 wherein the deflector 35 is shown in its two limiting positions. Figure 3 shows the device when the member 5| has its rearmost notch 55 engaging the ledge 49 of the opening 48 in the member 4|. At this point a further pulling of the rope 59 causes the projection 13 on the member 5| to engage the rearward end of the plate causing the plate 55 to have concurrent forward movement with the member 5|. This causes the dual notch 61 to shift in relationship to the flange 4'! of the bracket 4| whereupon the shallow slot 68 ultimately engages the ledge 49 of the opening 48, as shown in Fig. 6. The engagement of the top surface 14 of the plate 55 with the underside of the flange 53 of the member 5| has thus caused the member 5| to be raised out of proximity with the engaging ledge 49 of the bracket opening 48. This is true because the height between the shallow slot 68 and the top surface 14 of the plate 65 is greater than the height of the entire member 5|. Figure 6 shows the position of the device when the rope 59 is under tension and is being pulled by the operator. A subsequent releasing of the rope 59 will permit the member 5| to move to its rearmost position, as shown in Fig. 2. Intermediate the stopping of the device at the position of Fig. 2, the projection 12 on the forward portion of the member 5! has engaged the forward surface: it of the plate 65, causing the spring 62 to pull the plate 65 concurrently with the member 5| whereupon the plate 55 moves rearwardly so that the deep' slotsfl againexengagewthe*lower edge'lflller th-ibracketppening' 48.

It is '.thus=.apparent that the =-wagonelevator deflector 35, orx-for that matter-y any other 1 element :tmbe-remotelw adjustedj may be positioned inany one of a "series of: adjustable: positions .and' at the end of 'the *series of adjustments the device may be automatic'ally repositioned-for: the purposaofrepeating the availability of the series of increment-adjustments; an of which -isaccomplished by the successive pulling and releasing'of the 'pull rope' 59. The term rope comprehends anwfleiiible means 'such -as a cable, bhain',= wire or the like.

Numerous details of construction may be varied i peating the procedure when the series of increment adjustments is completed comprising a supporting structure, a bracket fixedly mounted on said supporting structure, said bracket having an opening therethrough, a member slidably positioned through said bracket opening, said member having a series of regularly spaced notches in the under side thereof for engagement with the lower edge of the bracket opening, spring means anchored to said supporting structure and to said member and arranged to urge said member in one direction through said bracket opening, a rope fastened to said member and arranged whereby a pulling thereof acts against the spring means to pull the member in notched increments through the bracket opening in the other direction, and means associated with said member and said opening to effect a raising of the member for releasing the member for sliding movement back through the bracket opening by reason of the action of the spring means.

2. A device as set forth in claim 1 in which each of the regularly spaced notches has an inclined surface and an adjoining vertical surface whereby a pulling of the rope causes the inclined surface of one of the member notches to ride over the lower edge of the bracket opening and to cause a succeeding notch to initially have its vertical surface engage the lower edge of the bracket opening.

3. A device as set forth in claim 2 in which said means associated with the member includes a plate having a dual notch in the underside thereof, said dual notch having a deep slot and a shallow slot, said plate from its shallow slot to its top side being greater in depth than said memher, said member having a flange on the upper edge thereof for sliding engagement on the underside by said plate, said plate throughout all regular notch advancement having its deep slot engaging the lower edge of the bracket opening,

and spaced projections on said member for engaging said plate to effect concurrent endwise travel of said plate with the member.

4. A device as set forth in claim 3 in which said spaced projections on the member are dis posed respectively forwardly of and rearwardly of the series of regularly spaced notches whereby the projection at the rearward end of the member causes the plate to be shifted forwardly when the member is moved forwardly by pulling of the rope and to have the shallow slot of the plate engage the lower edge of the bracket opening whereupon a releasing of the rope causes the spring means to return the member rearwardly its full length so that the forwardly disposed projection engages the front end of the plate causing it to be moved rearwardly with the member to the point where the deep slot engages the lower edge of the bracket opening and the first of the series of notches in the member again engages the lower edge of the bracket opening.

5. A remote control for an elevator load level ing hinged discharge flap comprising an elevator housing, a conveyor in said elevator housing arranged to deliver material to one end thereof for discharge, a deflector flap hinged in the discharge end of said elevator housing, and operating means for varying the angular position of said hinged deflector flap including a rope which upon successive pulling and releasing thereof causes the operating means to change the angular adjustment of the hinged deflector flap throughout a series of adjustments and means at the end of the range of increment adjustments including a spring for automatically repositioning said hinged flap at the beginning of said series of adjustments, and said means operable upon pulling and releasing of the rope.
